"While stopped at a traffic light at [[redacted]] and [[redacted]] taking a left turn, I pressed the gas to go through the intersection. The vehicle made a loud clunk sound and completely lost all drive power (driveshaft snapped). I had to manually push the car ('Flintstone it') out of the intersection to safety.". After losing all power during a left turn at [[redacted]] and [[redacted]], I coasted down and up a hill. Because the broken axle severed the transmission connection, the vehicle would not hold in Park, causing it to roll and end up facing the wrong direction on the wrong side of the street while waiting for a tow. The car was subsequently towed to the dealership for the recall repair." INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

because we were exposed to lightning, heavy rain, and unsafe conditions in a dark parking lot late at night. If the vehicle had failed in traffic or on the highway, it could have caused an accident or left us trapped in a hazardous location. The failure is unpredictable and has happened multiple times, making the vehicle unreliable and unsafe to operate. The symptoms match known electrical defects documented in Infiniti/Nissan Technical Service Bulletins, including IPDM failure, BCM communication faults, ECM relay malfunction, starter relay issues, and CAN communication errors. These failures can disable the vehicle without warning and prevent it from starting for extended periods. I am requesting an investigation into electrical system defects for this model year and VIN because this issue poses a serious safety risk to me, my child, and other drivers.

of the next cross street. I then had to back the car up at an angle in order to clear the next left turn. This enabled me to park on the right side curb while forcing the wheel to turn to the right. I needed to get my vehicle out of a busy street to safety. I turned the car on and off to check if the steering wheel unlocked and it remained locked. I was unable to drive the car so I called AAA and was towed to Infinity of Massepequa. I was told that I needed major work on the steering wheel system that will cost $5,605, parts and Labor. My car is a 2017 with only 50,000 miles on it. The 2014-2016 Infinity Q50's DAS systems were recalled for this exact steering problem. I asked the parts department about this recall and was told that my year car was not recalled. Given the frightening and dangerous incident and low mileage on the car, I think a recall is required on the 2017 model as well, given this harrowing experience. ISSUE 2: In December 2024 I paid $1,590 to repair the leaking sunroof on the Q50. When towed on [[redacted]], I mentioned ito the dealership that I still had leaking water in the car, again, a common problem with this infiniti model . I was told that they only repaired 2 of 4 drains originally at that time and repairing the other two was required and would cost an additional $1000-$2000. Again a product issue with this model Infiniti Q 50, on low mileage car. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

acceleration capability and began slowing significantly. Despite pressing the accelerator pedal, I was unable to maintain normal highway speed or accelerate. The vehicle continued operating at substantially reduced power, forcing me to drive at an unsafe speed relative to surrounding highway traffic. Following this incident, I brought the vehicle to an authorized Mercedes-Benz dealership for evaluation and repair. The service department confirmed that the vehicle had entered "limp mode" but was unable to determine the underlying cause. I was advised that no mechanical problem had been identified. The dealership performed several software updates and returned the vehicle to me, instructing me to monitor its performance. On October 18, 2026, while driving on the highway at approximately 70 mph, the same malfunction occurred again. The vehicle displayed a warning stating "Performance Extremely Limited," the check-engine light and turtle-shaped warning indicator illuminated, and electric driving mode became unavailable. This is now the second occurrence of this serious malfunction within six days, despite the vehicle having been evaluated by an authorized Mercedes-Benz dealership and receiving multiple software updates. The recurring malfunction presents a significant safety risk to the driver and surrounding motorists. The dealership has been unable to identify the root cause.

truck can begin shutting down and feel as if its stopping due to being stuck between gears or maybe torque converter. It happens on the highway at different speeds. It happens in city, stop and go traffic. The lunging forward comes into play with no prior warning. No lights, no messages on the instrument cluster. The dealer had me come in and drive the vehicle to show one of the managers what is happening while I am commuting. It has been confirmed EVERYTIME I was told there is no problem. I am attaching the latest work orders related to the issues after the engine replacement. For the past 6 months this truck is in the shop or stuck in my driveway more than it is driven or used. It is medically necessary that I have transportation available 24/7. I am under the care of several specialists since I was diagnosed and treatment for cancer began. Notice there are TWO work orders NUMBERED "63481" They are attached. ONE the third attempt dated (8-28-26) printed when i picked it up my ADAS was replaced and it has AVISRentCar, I paid for. Second "63481" forth attempt dated (9-15-26) printed when i picked it up after a Transmission relearn AGAIN (duplicate W.O. #) This one has Enterprise Rental I paid for. Now a FIFTH attempt to repair the same issue (9/21-9/29) This time they replaced the transmission valve body. Now, the truck is in the shop AGAIN, a Sixth time for the same problem. No issues found. I tested it again to show them. I am also attaching FTC report

system. The brake pedal instantly locked up, becoming rock-hard and completely unresponsive to mechanical pedal force. Due to the complete loss of power braking assist, the vehicle could not be slowed or stopped, causing a complete loss of vehicle control. This resulted in a vehicle spin, a structural collision/impact, and full airbag deployment. The vehicle's onboard diagnostic system caught this internal electronic component failure and transmitted an emergency brake system warning to my mobile app at [[redacted]]. CORRELATION TO KNOWN RECALL: This failure directly aligns with active NHTSA Recall 24V-104 for an internal electronic short-circuit within the Integrated Braking System module, causing a sudden, total loss of power braking assist. DEMAND FOR EVIDENCE PRESERVATION: I demand that all electronic control units (ECUs), Event Data Recorder (EDR) "black box" logs, freeze-frame failure data, and the Integrated Braking System module be safely preserved without modification, overwrite, or code-clearing for forensic data download and investigation INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

down again and required yet another transmission replacement, leaving me without my vehicle for several additional months. [[redacted]], my vehicle failed AGAIN while I was in Houston and had to be towed, proving that nearly a year of extensive repairs has failed to resolve these ongoing mechanical issues. This vehicle is a serious safety concern, and I have completely lost confidence in its reliability, especially after experiencing an engine fire, repeated breakdowns, and dangerous acceleration issues. I have continued making monthly payments on a vehicle that has spent more time in the repair shop than in my possession, causing significant financial strain, stress, and inconvenience. After nearly a year of unsuccessful repair attempts, I am demanding an immediate and permanent resolution, including a vehicle buyback or replacement, as I should not be expected to continue driving a vehicle that repeatedly jeopardizes my safety.

acceleration continued. Each time I eased off the brake, the engine revved to about 5,000 RPM or higher and the SUV accelerated rapidly, reaching about 85 mph or more. I had to brake extremely hard, smelled overheated brakes and made emergency lane changes to avoid collisions. No warning lights appeared. I stopped on the shoulder, still in Drive, and held the brake about 30 seconds. Upon releasing it, the SUV lunged forward aggressively again, unlike normal creeping in Drive. I braked and shifted to Park. I cannot confirm if the RPMs increased over 5000, but it aggressively, quickly lunged forward again. My husband drove it another 90 minutes, briefly engaging/disengaging cruise several times. He noticed hesitation or sputtering, especially uphill, but no repeat of the severe acceleration. A short drive the next morning without cruise was normal. Earlier [redacted], blind-spot mirror warnings failed to illuminate for about four passing vehicles, then resumed. A low key-fob battery alert appeared the prior week; a large windshield crack was noticed [redacted]. Connections are unknown. Nissan Roadside was contacted [redacted]. Tow/inspection is pending after an initial tow was canceled because the SUV would be left outside a locked dealer gate. The vehicle is available for inspection; no diagnosis yet. Please investigate unintended acceleration, brakes, throttle, ProPILOT/cruise and preserve any available electronic/event data. We narrowly avoided serious collisions.

filter were changed about 730 miles before the failure, with two more documented oil changes in the prior 16 months. Connecting-rod-bearing failure in this engine can cause engine seizure or stalling while driving, which creates a crash risk. The vehicle is at the dealer and has not been repaired. I am reporting this so NHTSA has a record of a Theta II failure in a vehicle covered by these campaigns that was denied repair.

cylinder 4, close to the exhaust valve. When I picked my car up from the dealership, I scanned the vehicle and found the P0303 cylinder 3 misfire code. I am concerned that the engine may have an unresolved problem that could cause it to overheat again, sustain further damage, or lose power while driving. The vehicle is still in my possession and available for inspection. I have an appointment with an independent mechanic on October 24, 2026, to have the engine and cooling system inspected and determine what may have caused the repeated overheating. I am submitting this complaint to bring attention to a potential engine or engine-cooling safety defect and ask NHTSA to consider whether similar problems may be affecting other vehicles.
